Abstract:

Most of the objectives of this research project have been achieved. In this first phase of the AFOSR grant 1 October 1998 - 30 September 2002, the principal investigator and his students have developed a 2-D unsteady compressible viscous magnetohydrodynamic code designated MHD2D which has been validated for 2-D internal and external flow The code solves the coupled MHD equations mass. momentum and energy equations of fluid flow including MHD effects Lorentz force and Joule heating, magnetic induction equations and Maxwell equations and includes an equilibrium air model for re gas effects, a finite-rate chemical kinetics model for dissociated air, several electrical conductivity models and a bi-temperature model. I-his code has been employed to investigate the concept of supersonic drag and heat transfer reduction by modificationdissipation of shock waves in the presence of strong magnetic fields. A series of numerical experiments for blunt body flows and scramjet inlet flow fields have been conducted by varying the Mach number, Reynolds number, degree of ionization of the air plasma and the intensity of the magnetic field to understand the physics of the phenomena and its potential for supersonic drag reduction in practical applications.
